Worcester Bosch Greenstar 8000 Life 30kW Combi Gas boiler frequently asked questions

Is this Worcester Bosch Greenstar 8000 Life 30kW boiler a combi, system or regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Worcester Bosch Greenstar 8000 Life 30kW boiler may be worth considering.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is the Worcester Bosch Greenstar 8000 Life 30kW combi boiler from the Greenstar 8000 Life range a suitable choice for my house or flat?

Whether this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler be appropriate for given its output of 30 kW?

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler would make it a suitable installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Worcester Bosch Greenstar 8000 Life 30kW Combi boiler's flow rate is 11 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Worcester Bosch Greenstar 8000 Life 30kW - size in millimetres

The Worcester Bosch Greenstar 8000 Life 30kW is 825 mm in height, 440 mm in width and 365 mm in depth.

Is the Worcester Bosch Greenstar 8000 Life 30kW condensing or non-condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Worcester Bosch Greenstar 8000 Life 30kW are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the combi Worcester Bosch Greenstar 8000 Life 30kW boiler energy efficient?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would choosing the Worcester Bosch Greenstar 8000 Life 30kW combi be an environmentally-friendly choice? If so, let's look at its performance figures.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Worcester Bosch Greenstar 8000 Life 30kW has been given a rating of 94% for energy efficiency, equivalent to a SEDBUK "A" rating.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Worcester Bosch Greenstar 8000 Life 30kW has a rating of "A" for heat and "A" for water.

Worcester Bosch Greenstar 8000 Life 30kW Combi Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Life 30kW a regular, combi or system boiler?

You might want to consider the Worcester Bosch Greenstar 8000 Life 30kW for your house or flat if you are looking for a combi boiler.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is the Worcester Bosch Greenstar 8000 Life 30kW combi boiler the right choice for my house or apartment?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Worcester Bosch Greenstar 8000 Life 30kW combi is 30 kW, so which types of property would this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler be appropriate for?

An experienced boiler engineer would recommend that this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler's flow rate is 11 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Worcester Bosch Greenstar 8000 Life 30kW dimensions

The size of the Worcester Bosch Greenstar 8000 Life 30kW boiler is 825 mm tall, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 30kW condensing or non-condensing?

The Worcester Bosch Greenstar 8000 Life 30kW is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

Is the Worcester Bosch Greenstar 8000 Life 30kW combi boiler rated as environmentally friendly?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Do the figures suggest that installing the Worcester Bosch Greenstar 8000 Life 30kW combi at your property would help in the fight against climate change?

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Worcester Bosch Greenstar 8000 Life 30kW has been given a rating of 94% for energy efficiency, equivalent to a SEDBUK "A" rating.

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar 8000 Life 30kW has a rating of "A" for heat and "A" for water.

How long is the warranty period on the Worcester Bosch Greenstar 8000 Life 30kW combi boiler?

The Worcester Bosch Greenstar 8000 Life 30kW boiler is covered by a parts and labour warranty of 8 years.
